Abstract: An apparatus includes a first member and a second member. The first member is configured to receive a portion of a syringe barrel and includes a first stop surface. The second member includes a second stop surface. Each stop surface is configured to engage the portion of a plunger to thereby arrest longitudinal movement of the plunger relative to the syringe barrel. The second member is operable to move relative to the first member from a first position to a second position. The second member remains coupled with the first member while in both the first position and the second position. The second stop surface engages the portion of the plunger when the second member is in the first position. The second stop surface does not prevent the portion of the plunger from reaching the first stop surface when the second member is in the second position.

Abstract: Luminaires are disclosed that include refractive and/or reflective structures that can provide or distribute lighting for a given area with high uniformity and efficiency. The structures can be used to distribute light from one or more light sources for lighting target areas with a desired light distribution. The lighting structures can be included in light strips or luminaires. Such luminaire can be utilized in place of fluorescent lights and can facilitate quick and easy retrofit for previous fluorescent lighting applications. The disclosed techniques and systems (including components and structures) can be particularly useful when employing one or more LEDs as light sources.
